Genre: Electric propulsion

Electric propulsion systems for space vehicles must be able to restart and operate at zero and low gravity. This operation can be achieved if the tankage delivers only single-phase propellants. The requirements for feed systems of electric engines are described briefly. Also, the 1.85-second drop- test facility is described and the testing techniques are discussed. The minimum energy principle is presented along with a method for determining the direction of mass transfer in tapered tubes and liquid-vapor interface shapes in an annular space between concentric cylinders. Possible feed systems for electric engines are given, which utilize surface tension for fluid positioning and transfer. Zero-gravity and static-fluid configurations in cylindrical and spherical containers are discussed along with experimental observations. The interface 'overshoot' of the equilibrium zero-gravity configuration is also discussed.

Criminality and Power in the Postcolonial City

This book investigates the literary imaginings of the postcolonial city through the lens of crime in texts set in Naples and Mumbai from the 1990s to the present. Employing the analogy of a ‘black hole,’ it posits the discourse on criminality as a way to investigate the contemporary spatial manifestations of coloniality and global capitalist urbanity. Despite their different histories, Mumbai and Naples have remarkable similarities. Both are port cities, ‘gateways’ to their countries and regional trade networks, and both are marked by extreme wealth and poverty. They are also the sites and symbolic battlegrounds for a wider struggle in which ‘the North exploits the South, and the South fights back.’ As one of the characters of the novel The Neapolitan Book of the Dead puts it, a narrativisation of the underworld allows for a ‘discovery of a different city from its forgotten corners.’ Crime provides a means to understand the relationship between space and society/culture in a number of cities across the Global South, by tracing a narrative of postcolonial urbanity that exposes the connections between exploitation and the ongoing ‘coloniality of power.’

On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever. Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead. At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.

Winner of the 1974 National Book Award "The most profound and accomplished American novel since the end of World War II." - The New Republic “A screaming comes across the sky. . .” A few months after the Germans’ secret V-2 rocket bombs begin falling on London, British Intelligence discovers that a map of the city pinpointing the sexual conquests of one Lieutenant Tyrone Slothrop, U.S. Army, corresponds identically to a map showing the V-2 impact sites. The implications of this discovery will launch Slothrop on an amazing journey across war-torn Europe, fleeing an international cabal of military-industrial superpowers, in search of the mysterious Rocket 00000.
